Project Applicant: 8 Mile Investments 236 (Pty) Ltd DEA&DP Reference Number: 16/3/3/1/D2/19/0024/19 Environmental Assessment Practitioner: CEN Integrated Environmental Management Unit 36 River Road, Walmer, Port Elizabeth, 6070 South Africa Phone (041) 581-2983 • Fax 086 504 2549 E-mail: [email protected] Date of submission : January 2020 ii Executive Summary Note: This is the Final Basic Assessment Report (FBAR) for the proposed establishment and operation of the George Airport Support Zone – the Draft BAR was sent for a 30 day public review period. For ease of reference, changes to the Draft BAR are highlighted in red text in this report. Activity Description 8 Mile Investments 236 (Pty) Ltd plans to establish warehousing, airport support services, and a filling station on Ptn 4 of the Farm Gwayang No. 208 in George. The proposed development requires that the site be rezoned from Agriculture 1 to Subdivisional Area, and subdivided into 14 erven to accommodate the following land uses: • One Business Zone VI erf to be used for a Filling Station comprising 1: • 4 dispenser islands for light vehicles • 1 dispenser island for heavy vehicles; • Three x 45 000 litre underground fuel storage tanks; • Convenience store / service station Shop; • Quick Service Restaurant / Take-away with limited seating; • Parking Bays (~19); • Ablution and Information Centre; • Internal service infrastructure that will connect to existing municipal services. • Seven Industrial Zone I erven to be used for warehousing and airport support services • One Transport Zone II erf to provide for a vehicular internal road network to the development, by means of an access and egress point off the R404. A new traffic circle is required at the access point, as part of the existing entrance to the George Airport; • Four Open Space Zone II including watercourses and the existing farm dam, that will form part of the stormwater management system for the development. • One Agricultural Zone I (the Remainder) reserved for the approved Western Bypass Highway across the eastern side of the site The development footprint will be ~6.37 ha. A site development plan is given in Error! Reference source not found. It is anticipated that construction would require approximately 5 years for completion. Underground fuel tanks may require upgrading or replacement after 20 years. 1 Should environmental approval for the development on Ptn 4 of Farm Gwayang No 208 be received, the developer will then apply for subdivision to give effect to the establishment of the filling station on a specified erf, as required by the Fuel Retailers Licence application. Figure i: Proposed Site Development Plan. Services A services report has been done by Studio 19 (Appendix 9). Supply of services to the development has been divided into 2 phases – the first being applicable to the filling station, and the second to the remaining 7 light industrial erven. Potable Water A new 160 mm uPVC pipeline will be installed to supply potable water from the existing municipal water supply line that runs along the R404 near the existing George airport entrance. The pipeline will need to traverse the R404, and a wayleave approval will be needed from the Provincial Roads Department. Shallow pipe depths at water course crossings (i.e. <1m) will need additional hard layer protection in the road design in order to protect pipes against stormwater and heavy vehicle damage. The estimated average water demand for Phase 1 and 2 is as follows: Phase 1 – business zone where water is needed for kitchen, toilets, wash up, and car wash = AADD = 20 kl/day @ 1.5 l/s peak flow and storage requirement [2x Average daily demand + Fire Storage (High Risk – 6 hours @ 1500l/min)] = 760m 3 Phase 2 – industrial zone where water is needed for warehouse toilets and wash up areas = AADD = 160 kl/day @ 1.5 l/s peak flow and storage requirement [2x Average daily demand + Fire Storage (Moderate Risk – 4 hours @ 1500l/min)] = 600m 3 To reduce pressure on the municipal water supply system, rainwater harvesting is planned for toilet flushing and garden irrigation. Sewerage Effluent from Phase 1 of the development will be transferred via a 110 mm uPVC gravity sewer collector line into a 160 mm uPVC gravity line that will cross the R404 to connect with the existing municipal sewer pump station near the existing entrance to the George Airport. A 63/110mm uPVC pump line will be constructed for Phase 2 of the development, which will discharge into the gravity sewer collector system. A new pump station will be required. The pump station will include a back-up pump / power supply and telemetric system that will automatically activate and sound an alarm in case of a pump and/or power failure. The pump station will incorporate a 24 hour response team that will monitor and attend to all maintenance issues. All emergency or accidental spills from the pump station will be discharged into an underground conservancy tank with a 48 hour storage capacity. Sewer lines will be positioned within proposed public access road reserves. All shallow pipe depths (i.e. <1m) at water course crossings will need additional hard layer protection in the road design to protect pipes against storm water and heavy vehicle damage. The following average daily wastewater quantities are expected from Phases 1 and 2: Phase 1: filling station and retail facility = 15 kl/day @ 0.15 l/s peak flow Phase 2: warehousing and airport services = 120 kl/day @ 1.2 l/s peak flow Solid Waste General solid waste from the development will be collected by the Municipality and disposed of at the transfer station in George, and from there to the proposed new district landfill site near Mossel Bay. Waste will be collected at enclosed waste service yards at each of the service station / light industrial erven that will be accessible from the access road. Solid waste quantities for commercial / light industrial purposes are based on an estimated solid general waste generation of 0.1kg/m 2/day: Phase 1: service station – estimated to generate approximately 100 kg/day Phase 2: light industries – estimated to generate 3500 kg/day. The Eden Municipality Integrated Waste Master Plan promotes reduction, re-use, and recycling of waste. In line with this, separate bins will be made available at waste service yards for recyclable materials. Bins will be emptied by a registered waste removal and recycling company. Hazardous waste in operational phase will be removed by a registered service provider in terms of the regulations of the Waste Act (Act No. 59 of 2008) and the Hazardous Substances Act (Act 5 of 1973). No burning, on-site burying or dumping of any type of waste will be allowed. Energy An Electrical Services Report has been done by Clinkscales Maughan-Brown (CMB) (Appendix 10). For long term planning purposes an electrical master plan has been compiled that includes Phases 1 and 2 of the development. The main supply to the development will also be undertaken in two phases - i.e. a supply of lower capacity and simplified construction for Phase 1, which is temporary, and of higher capacity and that is permanent to serve Phase 1 and 2 in terms of the master plan. Electrical supply to Phase 1 will connect to the existing municipal 16kVA pole mounted transformer substation on the Airport Line by means of an overhead line. A 200 kVA pole mounted transformer substation will be erected at this point for connection via 11 kV drop-out fuses and lightning arrestors to the 11 kV conductors of the Airport Line. For Phase 1 and 2 combined, it is proposed that a temporary 11 kV Ring Main Unit (RMU) be cut into the underground 11 kV cable between the Fancourt Substation and the Airport Substation, as the initial Point of Connection. The following energy saving mechanisms have been included in the development: Comply with SANS 10400. Energy efficient light fittings, air conditioning, mechanical ventilation, refrigeration and water heating installations, electric motors, etc. Use of LPG gas instead of electrical appliances for cooking where economically feasible. Use of energy efficient appliances. Building and plant load management systems to reduce power consumption in the case of the industrial erven. Installation of Photo Voltaic (PV) and other Small Scale Embedded Generators (SSEG) where it can be economically justified. It is expected that with the implementation of these measures, consumption will reduce by approximately 20%. Access A Traffic Impact Assessment has been done by Roodt Transport Safety (Pty) Ltd (Appendix 12). Current access to the site is a T-junction on route R404, opposite the existing entrance to the George Airport. The eastern part of the site is bisected by a proposed provincial trunk road TR 89 (Western Bypass). The extent of the road reserve for the Western Bypass is included in the proposed site development plan (SDP), with the remnant portion of the site to the east retaining its current agricultural zoning. The SDP provides access to the land-locked properties to the north and the south of the site. Access to the site is via a proposed single-lane roundabout at the intersection of the R404 and the existing Airport access road. The results of the capacity and operational analyses done in the TIA show that the proposed roundabout at the intersection can easily accommodate the expected additional vehicle trips, not only in terms of the design horizon year (2022), but also when the Airport Support Zone is fully developed for warehousing in the planning horizon year 2035.
